    If you visit Start> Administrative Tools> Licensing, you will be able to see what has been installed / setup already.

    In addition to the above however, it also depends on the method you used to purchase the licenses - If you used an open license agreement, the easiest way is to log on to the eopen MS site with the details your account was created with (this is often created on your behalf by the supplier you ordered the licenses from).

    The licensing feature in admin tools is often not accurate, as by no means do you have to 'install' the licenses for Windows Servers (and therefore they will not show up in the above) - You just need to own them in the first place, and be able to prove it. The server will not deny access to any of it's resources even if you haven't installed a single CAL.

    It's all based on trust, MS just expect you to own the correct number of licenses to cover all your users/computers connections to the box - If you don't have enough and they decide to audit you, you may get in trouble (or just be forced to buy enough licenses).

    At the end of the day, you need to be able to prove you own the licenses as well, as in you need to keep the confirmations you receive when you purchase them, or have them all registered on the eopen site.

    Even if you do own enough, but can't prove it (and the licensing tool in the first post does NOT count as any kind of proof) then you may as well not own them...

    So have a look at the eopen site (, and check with your accounts department for any invoices/receipts etc that can prove how many you've purchased. If you can't find the proof, you'll basically need to purchase them 'again'.
